Subreddit rules check
r/samplesize
Can you promote here?
The rules clearly permit sharing your own product or project. Follow the format norms below, disclose that it is yours, and lead with substance: allowed is not the same as welcomed for low-effort pitches.
From the rules · Use the subreddit flair tags (e.g. [Casual], [Academic], [Results]) and always state eligibility and time estimate.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: question, data, showcase
Headline: start with a bracketed tag ([Casual]/[Academic]/[Results]) + target group and age + short hook (e.g. “5‑minute anonymous burnout survey (18+)”). Write in first person when recruiting (I/we), keep body very short: eligibility, time estimate, purpose, and a link. Tone: factual, friendly, non‑salesy. What's rewarded: concise surveys with clear eligibility and interesting results writeups; blatant ads or unrelated marketing get ignored or downvoted.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked August 2026. Rules change and moderators have the final say: verify at r/samplesize's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
